Hi,

Think it would be great to go further and map the lifetime of the sun and explain Pamela's point about all the oceans evaporating in about 50 million years (which is when I think we do go Venus). The whole stellar birth, main sequence (with various fusion reactions explained) and ulimate red giant to white dwarf ending would be a fab. Still get the global warming thing in - but as a brief blip in the bigger story?
